Red, White, and Blue Noise
It is 2026.
America is two-fifty.
NASA isn’t just handing out fireworks. They sent up visuals instead.
Far away. Way outside US borders.
A collection of images. Videos too. All themed for July fourth.
They took data from the Chandra X-ray Observatory and the James Webb Space Telescope (JWTST). Then they colored it.
Red. White. Blue.
There is sound now too. Sonifications.
A fancy word for turning data into music. Usually it sounds eerie. Ethereal, maybe. Or just strange.
Cassiopeia A
Take a look at Cassiopeia A.
It sits 11,00 light-years from here.
It blew up a long time ago.
In these images?
X-rays are blue. Purple too.
Infrared wavelengths turn red. White.
The X-rays show the blast wave.
It is expanding. Spewing out calcium. Iron. Oxygen.
The infrared shows the shell. Growing.
Full of cosmic dust.
Does a supernova look like a firecracker?
Kind of.
But quieter. And darker.
Stars and Black Holes
Next is NGC 3603.
20,000 light-days away.
A huge star cluster inside a nebula.
Then there is Messier 94.
A spiral galaxy. 16 million light-years distant.
See that bright ring? That is a starburst ring.
New stars are forming there.
The audio maps things differently.
For Messier 94 they used a glass marimba.
Different pitches mean different objects. Neutron stars? High note.
Stellar-mass black holes? Lower.
For NGC 3603? Piano.
Brighter objects get specific notes.
Simple logic.
“Visuals and sounds mapped to celestial data.”
